Last I heard, the best gasoline engine out there was only 20, maybe 25% efficient at its very very best. Diesels, by nature of their combustion cycle, are a little better.

I could be wrong - I'm remembering from ten years ago and I haven't heard anybody give an efficiency rating since then. Then again, my ride is older than that and so are a lot of other folks' cars.

I'd give body parts to hit 33% efficiency.
That's the chemical release energy in Btus before any mechanical losses.About 66% of your fuel's energy goes out the tailpipe, or is lost to the cooling system.Some automobiles have efficiencies less than 20% overall.
